Application filed March 8, 1915. Serial No. 12,957.

ting shuttles, and aims to provide a tattin'g.

shuttle of novel and improved construction,

. whereby the bobbin may be readily removed for winding the yarn or thread thereupon, or for enabling one bobbin to be replaced by another.

It is the object of the invention to provide a tatting shuttle embodying a novel assemblage of the side members and bobbin, whereby they may be readily attached to and detached fromone another, for the intended purposes, and whereby the parts will be firmly held together when they are assembled.

Another object of the invention is the provision of a tatting shuttle having assembled therewith, a needle which may be projected or retracted to operative or inoperative positions, respectively, whereby the needle may be projected for use in taking up the thread or yarn when forming rings, and the like, so as to eliminate the use and bother of an extra pin or needle, and whereby when the needle is retracted, it will not interfere with the ordinary use of the shuttle.

It is also within the scope of the invention to provide a tatting shuttle having the im proved features above noted, and which is comparatively simple, compact, non-encumbering and inexpensive in construction, as well as being convenient, practical, serviceable and efficient in use. a

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the detailsof construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without. departing from the spirit of the invention. 1

The invention is illustrated in the accompanyingdrawing, wherein- Figure 1 is a plan view of the improved shuttle. Fig. 2 is alongitudinal section thereof taken on the line 2-2 of Fig. '1. Fig. 3 is a perspective view of one side member or plate of the shuttle. F ig.-4.- is a perspective view of the other side member or plate. Fig. 5 is a perspective view of the bobbin.

The present shuttle embodying a pair of slde members or plates 1 and 2, preferably constructed of sheet metal, which are of oblong or approximately elliptical contour, and which are curved so that their pointed ends lie close adjacent one another, to prevent the thread or yarn from passing too readily outward from between the side members, and to enable the shuttle to be readily passed back and forth during the tattingoperation.

The side members-l and 2 are detachably engaged to one another by a slip joint, and to this end an inwardly projecting tube 3 is soldered or otherwise secured to the central portion of the side member 1, and is provided at one side with a longitudinal slot or featherway 4, while an inwardly projecting tube 5 is solderedor otherwise secured to the central portion of the side member 2 and is provided at one side with a longitudinal feather 6. The tube 5 is tapered slightly from the basal to the free end thereof and is adapted to slip into the tube 3 and to slightly expand the same as the tube 5 enters the tube 3. The feather 6 is adapted to enter the slot or feather-way l when the tubes 3 and are telescoped together, which will hold the side members 1 and 2 against rotatory movement relative to one another, when they are assembled.

The bobbin 7 for holding the yarn or thread is preferably oblong or elliptical in form, so that the thread or yarn may be readily wound thereon, and in order that the bobbin will hold a comparatively large amount of thread or yarn thereupon. The bobbin 7 embodies the side members or plates 8 which are of elliptical contour. and which are connected by a'ceutral tube or hub t) and members 10. The tube or hub 9 has its ends engaged through the central portions of the side members or plates 8. The tube or hub 9 is provided with a longitudinal slot or featherway 11 which is adapted to register or coincide with the slot or featherwav t of the tube 3 when the hub 9 of the bobbin is slipped oi'er the tube 3. The side members or plates 8 of the bobbin are adapted to fit or rest snugly against the inner faces of the side members 1 and 2 when the parts are assembled.

To assemble the parts, the bobbin 7 is first i slipped over the tube or standard 3, with the slot or-featherway 11 of the bobbin registering with the slot or featherway 4. Then, the tube 5 of the side member is inserted into the tube 3, sothat the feather 6 enters the slots or featherways 4 and 11, and by pressing the side members together against the bobbin, the tube 5 will slightly expand the tube 3, to clamp the tube 3 within the hub 9 of the bobbin, and whereby the side members of the shuttle and the bobbin will be firmly bound or secured together, and will be prevented from accidental separation or displacement.

The side members of the shuttle may b readily separated by grasping them withthe thumb and fingers of the hands, and pulling the side ,members apart and by giving them a twisting motion at the same time, and when the side members are separated, the bobbin may be readily removed for rewinding the same, and for replacing the bobbin by another.

A number of bobbins may be employed in connection with the shuttle, the advantages of which are obvious to those versed in the art.

The tubes 3, 5 and 9 are preferably cylindrical or of circular cross section, but they can also be of square or other cross sectional outlines, without depreciating their value in the combination in which they enter.

The shuttle is also provided with a needle which may be normally retracted out of'the way, and which may be projected to operative position. To this end,'the adjacent ends of the side membersor plates 1 and 2 at one end of the shuttle are provided with 1on gitudinal outstruck grooves 12 which are opposed tov one another, and which cooperate to provide a throat for the passage of the needle therethrough. The side member or plate 1 is provided with a longitudinal slot 13 adjacent the groove 12, and a member 14 is disposed slidably against the inner face of the side member or plate lbelow or adjacent the slot 13, and is provided with a longitudinally outwardly projecting needle 15 extendingbetween the grooves 12 and curved slightly in order to project properly from the ends of the side members or plates 1 and 2 when the needle is projected. A shank 16 projects within the slot 13 and is riveted or otherwise secured to the member or. plate 14, i

and the shank 16 is provided with a button or knob 17 slidable upon the outer face of the side member or plate 1 over the slot 13, whereby the button 17 may be pressed by the thumb orfinger for retracting or projecting the needle 15. When the button 17 is slid longitudinally inward toward the center of the shuttle, the needle 15 will be retracted out of the way, and its point will be received by the groove 12 of the side member or plate 1 of the shuttle so that the needle will not interfere with the thread or yarn during the ordinary use of the shuttle. By pushing the button 17 toward the adjacent end of the shuttle, the needle 15 may be projected as seen in Fig. 2, whereby the needle may be employed for taking up the thread or yarn when forming rings or the like. This will enable the needle 15 to be quickly brought to operative position when desired, and eliminates the bother of using an extra pin or needle in connection with the shuttle.

The present shuttle may be used in the ordinary manner for tatting, as will be evident to those versed in the art, it being evident that the present shuttle is of advantage over the ordinary shuttle wherein the bobbin is not removable, since with the present device, the bobbin may be quickly removed for purpose of winding the yarn or thread thereon, or for enabling the bobbin to be replaced by another one having a new supply of the same or a different quality or grade of thread or yarn. The other advantages and attributes of the present shuttle will no doubt suggest themselves to those skilled in the art, and without further comment being necessary.

Having thus described the invention, what is claimed as new is:

1. A shuttle comprising a pair of s de members, one having a tube provided with a longitudinal slot, the other having a portion to enter the tube, the said portion having a longitud nal feather to enter the said slot, and a bobbin having a hub adapted to be slipped onto'the said tube, the hub having a featherway adapted to register. with the said slot and to receive the feather.

2. A shuttle comprising a pair of side members, one having an inwardly projecting hrb having a longitud nal featherway adapted to register with the said slot and to receive the feather, and the tube when expanded being adapted to bind within the hub of the bobb n.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
